Let's divide 151308 by 438
We want to divide 151308 by 438.

On to step 1:
438 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 438

Step 2:
438 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 438

On to step 3:
438 can be fit into 151 0 times, resulting in a remainder of 151.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 151 to get 151.
Take the next digit (3) from the dividend and append it to 151, then repeat: 1513 / 438

Advancing to step 4:
438 can be fit into 1513 3 times, resulting in a remainder of 199.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 1314 from 1513, we get 199.
Append the next digit (0) from the dividend to 199 and continue with: 1990 / 438

Let's proceed to step 5:
438 goes into 1990 4 times with a remainder of 238.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
The remainder is 238 after subtracting 1752 from 1990.
Include the next digit (8) from the dividend after 238, then repeat: 2388 / 438

Moving on to step 6:
438 goes into 2388 5 times with a remainder of 198.
Record the quotient 5 as the next digit in the result. 
Result so far: 345.0
The remainder is 198 after subtracting 2190 from 2388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 7:
If we divide 1980 by 438, we get 4 and a remainder of 228.
Put 4 as the next digit of the answer. 
Result so far: 345.4
Deduct 1752 from 1980 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 8:
When dividing 2280 by 438, we get 5 with a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 345.45
If we take 2190 away from 2280, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 9:
The number 438 fits into 900 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 345.452
Subtracting 876 from 900 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
438 can be fit into 240 0 times, resulting in a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 345.452
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
438 goes into 2400 5 times with a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 345.45205
If we take 2190 away from 2400, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 12:
2100 divided by 438 is 4 with a remainder of 348.
Use 4 as the next digit of our solution. 
Result so far: 345.452054
Subtracting 1752 from 2100 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 13:
438 can be fit into 3480 7 times, resulting in a remainder of 414.
Write down 7 as next digit of the result. 
Result so far: 345.4520547
Subtract 3066 from 3480 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 14:
438 can be fit into 4140 9 times, resulting in a remainder of 198.
The next digit of our result is 9. 
Result so far: 345.45205479
Subtract 3942 from 4140 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

After the division, we end up with 345.45205479 and a remainder of 1.98e-07.
